Commit d72ef888 introduced a bug in the libxl driver that will segfault libvirtd if libxl reports an error message, e.g. when attempting to initialize the driver on a non-Xen system. I assumed it was valid to pass a NULL logger to libxl_ctx_alloc(), but that is not the case since any errors associated with the ctx that are emitted by libxl will dereference the logger and crash libvirtd. Errors associated with the libxl driver-wide ctx could be useful for debugging anyway, so create a 'libxl-driver.log' to capture these errors.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
